摘要:

丛粒藻的游离烃类以C27—C33烯烃为主,还含有C13—C25正构烷烃、类异戊二烯烷烃(C15、C16、C18—C21)及微量甾烷、萜烷。丛粒藻真空热解烃类为C13—C35正构烷烃、类异戊二烯烷烃(C15、C16、C15—C21)及甾烷、萜烷。这些热解烃类的组成特征与胜利油田孤东地区上第三系含丛粒藻化石泥岩的烃类相似,从而首次证实了这些泥岩中的烃类主要是丛粒藻产生的。

Abstract:

The free hydrocarbon and vacuum pyrolyzed hydrocarbon of Botryococcus are analyzed by GC-MS system. The free hydrocarbon is mainly composed of C27-C33 alkenes,and also contains C13-C25 n-alkane, C15-C21 is oprenoid alkanes and trace sterane and terpane as well. The pyrolyzed hydrocarbon is C13-C36 n-alkanes, C15-C21is oprenoid alkanes, sterane and terpane. The author considers that the hydrocarbon of Botryococcus bearing Neogene mudstones in Gudong Region, Shengli Oilfield in Shandong, are generated by Botryococcus.
